Your roof is not meant to leak, period. But when a roof does leak it can cause significant damage to the building in which it is meant to protect.

We have just replaced a section of a tiled roof at Mazenod College in Lesmurdie as they had persistent and ongoing problems with the roof leaking. No matter what they did to address the issues, every year new leaks would appear. The main problem with the roof was the tiles.

This particular Swiss profile is notorious for leaks due to the design of the tile and their vulnerability to crack where you cannot see. Even having sarking under the tiles didn’t prevent the leaks as when the tiles were stripped off the roof, much of the sarking was damaged and riddled with holes.

The only long term solution for this type of roof is to remove the clay tiles and replace with Colorbond.

The final result looked great and the College can now look forward to winter with a leak free roof!
